What is the electrode potential for #Pb^(2+)(aq) + 2e^(-) rightleftharpoons Pb(s)# when the concentration of #Pb^(2+) (aq)# is #0.05# #mol# #dm^(-3)# ?
Temperature is 298 K and the standard electrode potential for the half-cell reaction is #-0.13# V.

-0.16 V
Explanation:
The expression for the electrode potential of a half - cell is:
For this half - cell at 298K this can be simplified to:
We would expect the potential to become more -ve like this since Le Chatelier's Principle predicts that reducing
